Actually, I wanted to know too. I think it uses a prism chipset, but I'm not 100% on that. If it does, it's supported. I almost bought one, but I've been browsing ebay and found a better deal then 35$ for a wireless CF card.

Recieved the card today, seems like a good adapter, worked out of the box on my SL-5500 running OZ 3.3.5. The adapter goes for $32, with shipping and tax (I live in CA) came to just over $40. Z says it's an "Orinoco or Prism 2"
